complex impedance cst
Hi everybody, now I am studying the lossy case of Line impedance
First I create a coaxial line with inner PEC radius=1 mm and outer PEC radius=3.83 mm
the material between the two PEC is vacum, that is epsilon=1 mu=1, no conductivity.
and the line impedance is exactly the same as the analytical result.
But when I set the conductivity of the material between the inner PEC cylinder and a outer PEC shell to a non zero value, say, 0.1s/m, the line impedance shown on the port mode screen will still be a real number. The analytical result must be a complex number.
I can only find the value of line impedance when I show the port mode.
So my question is can CST show the complex Line Impedance, both the real part and the imaginary part?
By the way , I also create a same model in HFSS, and it is able to give a curve of both real part and imagninary part that are in accordance with the analytical result.
Regards!
